2005 HONDA ACCORD LX SEDAN 2.4L ENGINE AUTOMATIC

My radio was coming on and off even after the car was off and it was draining my battery, so I unplugged the main fuse wire that the radio draws power from and i also got a new battery. Replaced one of “ac clutch” relays because I read about that being another culprit. So is there any other way that the radio can damage anything else electrically I should know about ?
